CLEANING MACHINE.

Application filed April 11,1925; Serial No. 22,382. Renewed' March 23, 1927'.

This invention contemplates the provision of a machine for cleaning cotton prior to its delivery to gin, and wherein the cotton is initially subjected to a heating to separate the bolls and dirt therefrom to a marked degree, while the burrs are fed longitudinally through the machine in both directions, and always subjected to the action of a plurality of revolving saws so that all'of the cotton is'sepa'rated from the burrs before the latter are discharged from the machine.

The nature and advantages of the invention will be better understood when the following detailed description is 'read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed. v

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and

wherein: I Figure 1 is a transverse sectional view through the machine. c

Figure2 is a. sectionalview' taken on line 2.-2 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 2. j

Referring to the drawings in detail, 10 represents a casing which may be of any suitable size and cross sectional contour, without departing from the spirit of themvention, Communicating with this" casing at one end thereof, is a hopper 11through which the cotton pass'esinto the casin'mlO. J ournalled within the casing 10 an arrangedlongitudinally thereof is agshaft 12,

and mounted on this shaft is'a plurality or 4 the dirt and other foreign matter therefrom,

which dirt and foreign matter fallsupon convey" thedirt and own-gara e matter through thelnachine to a discharge opening series of arms13,which are arrangedin spiral formation, the arms being of equal length and having their outer e'nds'oifset and flattened as indicated at 14. These armsare utilized to initially subject the cotton to r beatingoperation, witha view to separating at one end thereof, which opening is not,

herein shown;

Also journalled in the casing. to'one side" of the shaft 12 are spaced parallel shafts 18 and19 respectively, and these shafts are mounted to rotate in the same direction as the shaft 12, being suitably connected therewith by a suitable arrangementof belts and pulleys as indicated at the right of Figure casing in which the beater arms 13 operate. J

Consequently, the arms 13 beat the cotton against the saws20 as the initial step of the cleaning operation. Fixed upon the shaft 19 is a plurality of spaced disks 22 which operatebetween the adjacent saws 20, and the relative arrangement of the disks and' saws are clearly shown in Figure 1. Also journalled in the casing to one side of the shafts 18 and 19 respectively is ashaft 23 which supports a brush 24.- Wliicli rotates in the direction'of the saws and disks as indicated by the arrow in Figure 1. This brush takes the cotton frointhe saw teeth, and conveys it to'tlie beltdistributor, which in turn carries'the cotton" to the gin 25.

Jo urnalled' inthe casing and beneath the shaft 18 is a spiked conveyor including a shaft 26, the spikes 27 being arranged in spiral formation on the shaft 26, and of a length'to pass directly beneath the teeth 21 burrs, and completely separate therefrom' any cottontliat might not have been extracted from the burrs while the latter were be ing fed through'the machine by the'arms 13. Arranged above the spiral conveyor is'aiplurality of spaced parallel bars 28 which are connected with'side wall 29 to definetherewith a box like structure to hold the burrs associated with the spiral conveyor, while thesaws'20pick th'ecotton therefrom. Ar-

ranged beneath the spiked conveyor is a screen 30 through which the dirt and foreign matter falls iiito the channel like" bottom: 16

from where it is carried from the machine by means of a conveyor 17.

In practice, the cotton is initially depos ited in the casing 10 through the hopper 11, and at one end of the machine. The spiral beater arms 13 beat the cotton against the saws 20 to separate the dirt and other foreign matter therefrom, and also feed the cotton longitudinally through the casing from one to the other end thereof. During this operation a considerable quantity of cotton is picked from the burrs by the saws 20. and is carried by the saws and disks 22, in the direction of the brush 24, and inasmuch as this brush rotates in the direction opposite to the direction of rotation of the said saws and disks, the brush takes the cotton from the saws and delivers it to the distributing belt of the gin. While the cotton is being fed in the direction just mentioned, and subjected to the beating operation of the arms 14-, the bolls are torn to pieces between the teeth of the saw and the arms 13. Of course, the disks 22 are closely related to the saws 20 and assist the latter in pulling the cotton from the burrs and also from that part of the casing in which the cotton is initially deposited. The burrs however, are prevented from passing between the saws and disks, the saws kicking or knocking the burrs back into that part of the casing in which they were initially deposited, and after the burrs reach the very end of the casing, as compared to the location of the hopper 11, the burrs enter the boX like structure above defined and in which the spiked conveyor operates. This conveyor then feeds the burrs in an opposite direction longitudinally through the casing to subject the burrs to a recleaning operation, and while the burrs are moving in this direction, they are again subjected to the action of the saws 20 which extract all of the cotton therefrom, pulling the cotton between the spaced parallel bars 28 which hold the burrs associated with the spiked conveyor for the purpose mentioned. As the burrs reach the end of the spiked conveyor in their direction of travel, they are discharged from the machine through a suitable opening therein, not shown. It will be noted that the beater arms 13, saws 20, disks 522, the spiked conveyor, and the conveyor 17 in the lower end of the machine are rotated in one direction as indicated by the arrows in Figure 1, while the brush 24 rotates in an opposite direction for the purpose above mentioned.

YVhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, we desire to have it. understood that we do not limit ourselves to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.
